About Polymer Research and Bruker
We are Deeply Rooted in Polymer Research
聚合物材料的多功能性几乎是传奇的，高性能塑料的兴起已永必威手机客户端久改变了许多工业领域。必威东盟体育对新塑料的研究是一个使布鲁克忙了数十年的话题。我们为所有研究任务提供广泛而强大的技术组合，以与下一代聚合物保持同步。
Polymer Fillers
Identification of Inorganic Filler Materials in Polymer using FT-IR
Inorganic salts such as ammonium polyphosphate or titanium dioxide are frequently used as polymer filler materials to improve the processability, optical properties or fire retardancy.
完全表征这种复合聚合物并仅使用FT-IR技术识别无机填充剂（MIR 400-4000 cm-1) spectral range is not sufficient. Whereas the MIR range delivers information to identify the polymeric host materials, additional far infrared (FIR below 400 cm-1）区域揭示了有关填充剂中无机离子化合物的晶格振动的重要信息。
布鲁克（Bruker）用于FT-IR R＆D光谱仪的独特FM技术合并MIR和FIR光谱范围，并实现了6000 - 50厘米的测量-1在一次扫描中，无需交换任何光学组件（这是将光谱范围扩展到FIR的强制性）。在这里查找，Bruker FM如何简化聚合物表征。
拉曼成像中聚酰胺6中的阻燃性分布
Flame retardants are key ingredients in polymers used forconstruction and engineering. Without them, safety issues would be tremendous as some polymers exhibit significant flameability. In some materials, flame retardants can make up to 30%of the polymer formulation!
不正确distribution of such addtivies can lead to critical comprizing基本材料的影响。The Figureshows the chemicalRaman imageof the distribution of the halogen free flameretardant melamine cyanurate (MC) in a polyamide-6 matrix.
Obviously, the flame retardant has not migrated through the entire material and has formed clusters and void zones. Although the grain size is homogeneous, the overall result is not satisfactory and the process must be optimized.
New Material Characterization
Polymer Crystallinity and Crystallization Kinetics by TD-NMR
半晶聚合物在材料科学，技术和自然中起关键作用。必威手机客户端所有合成聚合物的大约三分之二具有结晶的能力，这就是使这些材料作为模制零件，膜或纤维的多样化使用的原因。必威手机客户端
With TD-NMR it is possible to obtain information about the bulk crystallinity and crystallization kinetics of the most important synthetic semi-crystalline polymers. By determining the temperature-dependent relaxation behavior, an unambiguous determination of the polymer crystallinity is possible. In addition, isothermal crystallization can be monitored.
TD-NMR允许表征聚合物的大量结晶度和结晶动力学，这预测了用于研究，质量控制和加工实验室的技术。
Characterizing Material Properties by FT-IR and Thermogravimetric Analysis
热分析仪收集依赖温度依赖的质量变化（热重法），焓值（差异扫描量热法）或两者的组合的信息。另一方面，FT-IR收集光谱（分子）信息。
FT-IR与热分析相结合可以帮助阐明新聚合物材料的基本热行为。必威手机客户端使用它来分析：
- Decomposition behavior of substances
- Evolved gases during decomposition
- Residual solvents (Identification and Quantification)
- Phase transition temperatures (melting point, glass transition, etc.)
- 水吸附和迁移
Monitoring Catalyst Activity by FT-IR
Catalysts play a fundamental role in polymer research and synthesis and understanding the chemical reaction processes is vital to increase yield, efficiency of functionality of the desired polymers.
FT-IR can be used to characterize catalysts, their behavior and chemical reactions involved. Time-resolved measurements with up to 110 spectra per second allow you to analyze catalytic processes into the low microsecond domain.
With Step Scan, Rapid Scan and Interleaved TRS, powerful Bruker tools are available to elucidate any kind of dynamic processes such as chemical or physical reactions.
